Single‐molecule junctions have been of particular interest in molecular electronics. Toward the realization of molecular electronic devices, it is crucial that functional single‐molecule junctions are connected to each other using joint units on the atomic scale. However, appropriate joint units have not been reported, because controlling the charge transport direction through the junctions is not trivial. Here, the authors report a joint unit that controls and changes charge transport direction through the junctions, by using ruthenium tris‐bipyridine (RuBpy) complex. The RuBpy single‐molecule junction was fabricated between gold electrodes using scanning tunneling microscopy‐based break junction techniques. The RuBpy single‐molecule junction showed distinct low and high conductance states, in which electronic charge is transported linearly and vertically through the RuBpy complex.
